No. 31,762. Patented Mar. 19, 1861..

YVM. H. HOPE, OF YVASHINGION, DISTRICT OF COLUMBIA, ASSIGNOR TO THOMASB. FLORENCE, OF PHlLADELPI-IIA, PENNSYLVANIA.

MACHINE FOR. SWEEPING STREETS.

To all whom it may concern:

Be it known that I, l/VM. H. Horn, of WVashington, in the District ofColumbia, have invented a new and Improved Mode of Cleaning or SweepingStreets; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon.

The nature of my invention consists in the arrangement of a cylindricalbrush revolving in a metallic, or other adjustable casing, whereby thedirt is gathered from. the streets, lanes, or alleys, and thrown intothe close box or body of the machine, that can be carried off andemptied at some convenient place when a full load' is collected.

It also consists in the arrangement of lever L, in combination with theaxle A, bar R and connecting rods 1' 1', whereby the brush is thrown outof gear when it is necessary to remove the machine to some distant placeto empty its load.

In the drawings Figure 1 shows a perspective view of the machine. Fig. 2a top view and Fig. 3 a side view.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

W W show the large wheels on which rest the body and other parts of themachine.

C C are the. cogs on wheel WV in which the cogs of small cog wheel tomesh, or work, for the purpose of driving the brush B, said brush Bbeing made of cylindrical form, of hickory splits, or other similarmaterial, and revolves in casing a a, which casing a a; is madeadjustable so as to be placed up to the brush B as said brush wearsaway. This casing a a encircles about one-half the brush, commencingnear, or on the ground and ending at the top center of brush B; theobject of this casing is to enable the brush B to convey the dirt, orsweepings, into the box 6 or body of the machine.

2' i, show the places where the adjustable casing is attached to thebody of the machine.

c is an adjustable partition, which is made to work to the brush B andseparates which connect R and L with axle A. Lever L, cross bar R androds 7 1" are so connected with box I) and axle A A as to move box 5when it is necessary to ungear the brush B.

s is the slot in box 5 in which axle A moves.

Z shows a lever which the driver works with his foot when necessary toraise the brush B from the ground, or lower the same.

If is the hinged top, or cover, which is used for keepingthe dustconfined when the machine is in operation and to enable the driver tosee the contents of the box 6.

S is the drivers seat and s s the shafts.

r 7" are small ratchet bars used for the purpose of holding partition 2'i in place, partition 2' 2' being hinged or made movable at its bottom.

to w are small wheels seen in front of the machine, intended to bear thebrush from the ground and prevent it (the brush B) from bearing too hardon the ground, or pavement. Said wheels may be made adjustable so as tobe raised, or lowered, as the brush B wears away. The brush B is soarranged in its bearings that it can be turned end for end, whennecessary, or easily taken out for repair, &c.

h h are handles, to be used when it may be necessary to use the machineby man instead of horse power.

The principles of this machine may be applied to a four wheeled twohorse vehicle, or machine, as well as to such a. one as is abovedescribed and shown in the drawings.

This machine differs from all other street sweeping machines, inasmuchas but a single re\*olving brush, running in an adjustable half casing,is used to convey the dirt, immediately into a close box which isemptied from its bottom. Also in the mode of gearing and ungearing thebrush and the combi nation and arrangement of other parts of themachine. I

Therefore what I claim and desire to secure by Letters Patent is:

1. The arrangement of acylindrical brush, in street sweepers, revolvingin a metallic,

or other, adjustable casing, as described, axle A, which are attached tobox, or body, whereby dirt and other substances are gathb for thepurpose of ungearing brush B, as ered, Without any other mode ofconveyance, set forth and described.

into the box or body of the machine, as set WM. H. HOPE.

5 forth and described. Witnesses:

2. The arrangement of lever L in combi- \VM. LITTLE, nation with bar R,connecting rods 1' r and Jo. SEVERNS.
